So far it is around 10.2.1. Don't even try to upgrade it as Chinese characters will fail in parallel view and the author Rick Meyers, though as generous as he is talented, didn't seem that interested to deal with the fix when I reached out to him years ago. I tried to take a crack at the codes myself, but it's better just to stick with the older version, good thing I saved a copy of the old installer. And I'm not missing out on anything new with this old one.
I need the parallel view with Chinese to not only improve my Chinese but for hermeneutic reasons as well.
